Default basic fuel help

Fuel is my limiting factor at this point. Let's just plan for N/A since I'll be juicing a wet shot.

I need a f-body fuel system crash course to choose injector sizes and fitments, fuel rail and line capacities, pressures, and pumps.

Stock cubed LS1 with TRex cam, 92/92 TB/Fast Intake, and ported heads.

Thanks, I just shot them an email. Does anybody have any non-salesman (unbiased) advice?

Not sure if you consider my opinion biased but here is some factual data.

A single 255 pump will support around 550rwhp.
A wet shot on nitrous will not effect the injector requirements.

Injector flow is roughly .5#/hr per hp. normally aspirated.
So a 500hp engine needs approx 250#/hr divided by 8 injectors or about 31# per injector (at your rated pressure). You should have at least 20% additional capacity, so you would need approximately a 38# injector minimum for 500hp. Yous some ballpark figures, but you can get the idea.

Lines & rails are good for pretty serious power. Your should not have any problems under 650rwhp... then your rear mount regulator will fail to properly control your pressure. Big nitrous hits can also be troublesome with the factory regulator... typically over 150hp.

I stock many pumps, injectors, rails, regulators & line kits to meet any of your performance needs.
Feel free to give me a call if you need any assistance.

That's exactly the info I have been searching for

If your Info address doesn't respond to my email by Wednesday afternoon I'll give you a call. How fast do orders usually take from payment to doorstep (I'm in TX)?

Typically 3 days to TX.

...But I recommend you call for more info. A few minute phone call will accomplish a lot towards determining your best setup.

Just got off the phone with Lonnie (a few times) and he really answered my questions well. My questions got kinda repetitive but its the only way I know to weigh my options. And he was cool the whole time explaining things simple enough yet detailed enough that I understand how and why it works, if that makes sense.

Anyways, he won my sale and I feel like the 'expert premium' is justified in this purchase

Glad I could be of help.

As you probably noticed, I will not try to sell you something you do not need, or something unsuitable to your application just to make a sale.

I'm sure you will feel you got your moneys worth when you see the kit.
